Final answer:
To find the reduced length of the square Toy Story poster, we multiply the original length (18 inches) by the scale factor (1/5), resulting in a reduced length of 3.6 inches.
Step-by-step explanation:
The question asks us to calculate the reduced length of a square Toy Story poster when scaled down by a factor of 1/5. The original length of the poster is given as 18 inches. To find the reduced length, we multiply the original length by the scale factor:
- Original Length: 18 inches
- Scale Factor: 1/5
Reduced Length = Original Length × Scale Factor
Reduced Length = 18 inches × 1/5
Reduced Length = 18/5 inches
Reduced Length = 3.6 inches
The reduced length of the poster is 3.6 inches.
